To all whom it may concern: 7

Be it known that I, JAMES H, GEORGE, a citizen of the United States, and a resident of the borough of Manhattan, city, county, and State of New York, have invented a certain new and useful Improvement in Metallic Barrels, of which the following is a specification.

My invention relates to metallic packing and storing vessels designed for the shipment of liquids such as petroleum products, and more particularly to that type of such vessel which may be knocked down and the parts nested for transportation when empty.

My object is to provide a knock-down vessel for the shipment-of liquids which will be strong and durable in use, will be unleakable, will be readily knocked down and reassembled and which is composed of a minimum number of parts, and which has few joints.

These and further objects will more fully appear in the following specification and accompanying drawings considered together or separately.

I have illustrated my invention in the following drawings in which like parts are indicated by similar reference characters in all of the several figures, and in which,

Figure 1 is longitudinal section of a tlon.

wing 4. The wings? and 4; are of a length less than that of the staves for a purpose to be hereinafter described. The wing 23 of each stave is slitted at intervals to produce tongues 5, and at points corresponding to the tongues slots 6 are cut or otherwise formed at the base of the wing t. The slots are so proportioned that the tongues 5 of the coiiperating stave when bent at right angles to the wing may freely enter them. The wing 3 is bent inwardly at substantially a right angle to-the edge of the stave. The tongues 5 are bent inwardly a distance equal to about the thickness of the metal of the barrel and then bent forward on a line parallel to the transverse curve of the stave and lying within the boundary of the stave, a distance at least equal to the thickness of the tongue. The tongues therefore project beyond the edge of the stave and in proximity to the adjoining stave. The wing 4 of each stave is bent inward at approximatelya right angle to the edge of the stave.

The ends of the stave are bent inward and thendownward to form an annular inturned rim-7 and the inner extremity of the rim is rolled to form a recess or croze 8. The stave" is provided near each end with a peripheral groove or recess 9 and the base of the metal displaced to form the groove 9 contacts with the metal displaced to form the recess 8. This constialction will effectually prevent the rim 7 from springing outwardly. Additional grooves are formed in the stave as shown at 9 I provide a sealing strip 10of a yielding material which will not be affected by the contents of the barrel. I have found that asbestos is a material well adapted for this purpose although other materials, animal, vegetable or mineral, may be employed. The strip is preferably cut to the shape shown in Fig. 2 with slots 11 and notches 12. A strip is placed on each wing 3 with the tongues 5 projecting. through the slots l1. The extremities of the strip he against the edges of the stave and annulus and the notches 12 will coincide with the recesses 8.

A pair of staves formed as above described are assembled with the wing 3 of one stave, carrying thestrip 10, in contact with the wing 4 of the other stave, and with the tongues 5 pro}eeting through the slots 6. hoopsii are now driventowaifd the bilge of the barrel soformed frjom each end. The hoops are driven down they cover the sealing strips to parts may now terior circumferential groove.

ing force be the grooves 9 A center punch is now driven into each hoop 13 at intervals thus forcing the material of the hoop into the groove as at 14:. The driving of the hoops will draw the staves to ether and compress joint between the staves.

- A gasket 15 is now placed in each end of the barrel and rests within the croze 8. This gasket is preferably provided with an in- A head 16 is now sprung into the groove in the gasket whereby an unleakable joint is formed between the annular rim of the staves and thehead.

In connection with my improved barrel I provide a seamless annular end cap or hoop 17. The end cap or hoop is composed of an outer flange 18 which conforms in shape to the outer contour of the end of the barrel and an inner flange 19. The end .cap or hoopis driven on the end of the barrel until the flange 19 contacts with the outer surface of the head 16, and as the flanges 18 and 19 have a driving fit with the outer sur- .face of the barrel and the rim 7 respectively, a strong and rigid structure is produced. The engagement of the flange 19 with the inner surface of the extension will cover the joints between the staves and prevent the ends of the sealing strips 10 from being displaced.

In order to prevent accidental displacement of the end cap or hoop a set screw 20 may be inserted through the end hoop and engage within the groove 9. The head of the set screw will be flush with the outer surface of the hoop.

In the modification shown in Fig. 9 the upper edge of each stave is turned over to form a flange 21 and the head22 is in the form of; a seamless cup having a cylindrical wall 23 and an outwardly projecting peripheral flange 24. A gasket 25 is placed on the flanges 21 of the staves when the latter are assembled and the flange 24 rests upon the gasket. When the end hoop is driven in place the head will be securely held in position and the gasket will prevent leakage. If desired in the form shown in Fig. 9 the 17 may be omitted. The grooves or corrugations 9 and 9'? in addition to the uses above pointed out act to strengthen the barrel and as they are concealed by the hoops 13 and 17 the exterior of the barrel. presents an unbroken. surface.

When it is desired to' pack the barrel for shipment when empty. the set screws 20 are removed and the-end hoop driven off. The body hoops 13- are then driven off, the driving 'suflicient to iron out the points 14 made by the center punch. The be separated and nested for shipment.

'- While I'have shown my orm an unleakable ing tongues on each extension being of less improved barrel as composed of two staves, I desire to have it understood that I do not wish to limit myself to such construction and the number of staves may be increased without departing from the spir't or scope of my invention.

Instead of using a punch mark to retain the body hoops 13 in position I may employ set screws similar to those shown at 20 for securing the end hoops in place.

In accordance with the provisions of the patent statutes I have described the principle of my invention, together with the apparatus which I now the best embodiment thereof, but I desire to have it understood that the apparatus shown is merely illustrative, and that the invention may be carried out in other ways.
